Thanks for the feedback. I checked with Nano and VIM and they render
fine (though a small problem is that the "action" is often hidden from
view as the initial text manipulation happens in the top of the
screen, which remains out of the viewport in the shared terminal
view). I like your ideas on utilizing the tab mechanism for N-N
sharing, since at the moment, the sharing happens blindly in 1->N
fashion from the first tab only, which I think is a bit clumsy.

I think I'll propose read only shared terminal as a feature for 0.88
Thanks again,
